Javascript: add a character to a string containing a specific word

Question

If I have the following string: table.row.columns.values.many. I am looking to add character * after values. So expected output would be: table.row.columns.values*.many . If there is no "values" in string then string should stay the same.

Use replace? It’s unclear what the specific issue is since this should be easy to search for. — Dave Newton

Yeah I can test for "values" and replace it with "values*" but idk if that is right — Gurbaz Pooran

@GurbazPooran It’s right if it works. This is easy to test in a console or NodeJS REPL (console). — Dave Newton

Please use this code.

let str = "table.row.columns.values.many"
str = str.replace("values", "values*");
console.log(str);

You can use also "replaceAll" if you want to replace all "values".

I think this works nice for you, really simple, and easy way

var str = "table.row.columns.values.many";
str = str.replace("values", "values*")

console.log(str)

this doesn't work. replace returns another string. If you want to change the original string you need to assign the 'replace' string to the initial string. str = str.replace(....)

Yeah, now i've did some changes on the code, but nevermind, the right answer is on the top...
